DETAILED DESCRIPTION

Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.

According to an exemplary embodiment, the off-road vehicle of the present disclosure includes components that facilitate increasing the payload capacity rating thereof relative to utility task vehicles (“UTVs”) (e.g., which may have a payload capacity rating of 1,500 pounds or less, etc.). By way of example, the off-road vehicle of the present disclosure may have a payload capacity rating greater than 1,500 pounds (e.g., 1,750 pounds, 2,000 pounds, 2,500 pounds, 2,800 pounds, 3,000 pounds, 3,200 pounds, etc.) and/or a towing capacity greater than 1000 pounds (e.g., 1,250 pounds, 1,500 pounds, 2,000 pounds, 2,500 pounds, 3,000 pounds, etc.). The off-road vehicle of the present disclosure may additionally or alternatively have an increased width relative to UTVs. By way of example, UTVs may have a maximum width of less than 65 inches in order to comply with department of natural resource (“DNR”) regulations for trail riding, while the off-road vehicle of the present disclosure may have a width of between 60 inches and 80 inches (e.g., 60 inches, 65 inches, 68 inches, 70 inches, 72 inches, 74 inches, 80 inches, etc.). Thus, the off-road vehicles of the present disclosure are different from UTVs at least in that they (i) have specifically-tailored components that facilitate providing increased payload capacity and/or (ii) are wider. Such off-road vehicles provide significant advantages relative to and/or provide solutions in markets not serviced by UTVs (e.g., utility in construction applications, utility in fire and emergency applications, utility in military applications, etc.). In other embodiments, the off-road vehicle of the present disclosure is another type of vehicle such as a recreational off-highway vehicle, an all-terrain vehicle (“ATV”), a golf cart, and/or still another vehicle.

According to an exemplary embodiment, the off-road vehicle of the present disclosure includes a cab assembly and a hood, cargo, and storage assembly both supported by a chassis. The hood, cargo, and storage assembly includes a hood and a grille (e.g., a brush guard, etc.). Traditionally, off-road vehicles include stylistic, plastic hoods that provide minimal functional protection to components of the vehicle. A separate brush guard may be attached to the front of the chassis of traditional off-road vehicles to protect not only the components under the hood, but the hood itself. The hood of the present disclosure is manufactured from metal and/or plastic (e.g., sheet metal, sheet metal with an outer plastic skin, etc.), and the grille is manufactured from tubular metal. The grille is coupled directly to the hood (e.g., welded, bolted, etc.), and the assembly provides a structurally rigid fascia that does not require a separate brush guard to protect the components under the hood and the hood itself. The cab of the present disclosure may accommodate three bucket seats or a three-person bench seat laterally across the cab. The cab of the present disclosure may also have a roof assembly including a roof panel and a frame. The frame supports the roof panel, but the roof panel itself may have a subframe. A distal end of the roof assembly (e.g., a distal portion of the roof panel, etc.) overhangs a rear section of the cab (e.g., the roof panel may extend beyond the frame, etc.) without a support structure supporting the distal end thereof (e.g., without a C-pillar, etc.).

According to an exemplary embodiment, the off-road vehicle of the present disclosure includes interchangeable rear modules. A first rear module may include a reconfigurable cargo bed module having a cargo bed and a seating assembly. The seating assembly is selectively reconfigurable to extend the cargo bed. A second module may include passenger seating and litter carrying module including multi-purpose seats. The multi-purpose seats are selectively reconfigurable to accommodate both seated passengers and a litter.

According to an exemplary embodiment, the off-road vehicle of the present disclosure includes three axles, namely a front axle (e.g., the number one axle, etc.), a first rear axle (e.g., the number two axle, etc.), and a second rear axle (e.g., the number three axle, etc.). Each of the front axle, the first rear axle, and the second rear axle may be driven by a powertrain of the vehicle. The powertrain includes a primary driver (e.g., an engine, a motor, etc.), a transmission, a transaxle, a rear drive shaft, a rear differential, a front drive shaft, and a front differential, according to an exemplary embodiment. The transmission couples the engine to the transaxle, the rear drive shaft couples the transaxle to the rear differential, and the front drive shaft couples the rear differential to the front differential. In other embodiments, the off-road vehicle does not include a transaxle (e.g., includes another differential, includes a transfer case, etc.). The engine provides a mechanical energy output to the transmission that is provided to the transaxle by the transmission. The transaxle provides (i) a first portion of the mechanical energy received from the transmission to the second rear axle to drive the second rear axle and (ii) a second portion of the mechanical energy received from the transmission to the rear differential. In some embodiments, the transaxle is positioned forward of the second rear axle and rearward of the first rear axle. The rear differential provides (i) a first portion of the mechanical energy received from the transaxle to the first rear axle to drive the first rear axle and (ii) a second portion of the mechanical energy received from the transaxle to the front differential. The rear differential may thereby be referred to as a drive-through differential as the rear differential not only drives the first rear axle, but also the front differential. The front differential provides the mechanical energy received from the rear differential to the front axle to drive the front axle.

According to an exemplary embodiment, the off-road vehicle of the present disclosure includes a cooling system having a radiator disposed underneath a hood of the vehicle. Traditionally, radiators provided with UTVs are arranged in a vertical orientation. Arranging such radiators in a vertical orientation may require the hood line (e.g., the side profile of the hood, etc.) to be elevated to fit the radiator at the front of the UTV, negatively affecting the visibility of the operator and therefore the drivability of the UTV. The hood line may need to be elevated due at least in part to (i) the fixed vertical position of the chassis and/or frame of the vehicle (i.e., the radiator may not be positioned lower due to interference with and/or support thereof by the frame) and/or (ii) the set width of the space claim available for the radiator (i.e., body panels, lights, etc. provided with UTVs may limit the lateral width available for the radiator). The radiator may thereby need to be taller than desired in order to satisfy the cooling requirements of the engine and/or the powertrain of UTVs. The hood covers the radiator (e.g., for aesthetics, for protection, etc.), and covering the taller radiator thereby may require elevating the hood line. To reduce the elevation of the hood line, radiators may be positioned further rearward. However, positioning radiators further rearward may negatively affect the performance of the radiator. The cooling system of the off-road vehicle of the present disclosure includes a bracket configured to orient the radiator at an angle (e.g., relative to a vertical axis, relative to an axis that is perpendicular to an axis defined by a chassis of the off-road vehicle, not perpendicular to an axis defined by a chassis of the off-road vehicle, etc.). The angularly offset radiator may facilitate (i) positioning the radiator at the front end of the vehicle, (ii) lowering the hood line of the hood to increase operator visibility, and thus the drivability of the vehicle, and/or (iii) maintaining or increasing the cooling capacity of the cooling system (e.g., by increasing the size of the radiator, etc.).

According to an exemplary embodiment, the off-road vehicle has a braking system that includes a parking brake assembly. In one embodiment, the parking brake assembly includes (i) a first parking brake that facilitates selectively actuating a first braking assembly associated with the first rear axle and (ii) a second parking brake that facilitates selectively actuating a second braking assembly associated with the second rear axle. The vehicle may additionally or alternatively include a steering system that has a steering rack with an input that is spaced from an end of the steering rack and is disposed toward a center of the vehicle.

Overview

According to the exemplary embodiment shown in FIGS. 1-7, a vehicle, shown as vehicle 100, includes a chassis, shown as frame 200. The vehicle 100 also includes a body assembly including a first portion, shown as cab 400, and a second portion, shown as rear module 600. The cab 400 and the rear module 600 are coupled to the frame 200, according to an exemplary embodiment.

As shown in FIGS. 1-3,6, and 7, the rear module 600 is disposed behind the cab 400. By way of example, the rear module 600 may be disposed behind the cab 400 relative to a forward travel direction of the vehicle 100. The vehicle 100 may be configured to have a greater top speed in the forward travel direction than in a reverse travel direction. The vehicle 100 may additionally or alternatively have a windshield configured to deflect an airflow otherwise incident upon the driver of the vehicle 100 when moving in the forward travel direction.

As shown in FIG. 3, the vehicle 100 includes a drive system, shown as powertrain 800; a thermal management system, shown as cooling system 1000; a braking system, shown as braking system 1200; and a steering system, shown as steering assembly 1400. The powertrain 800 may include a primary driver such as an engine, a transaxle, a differential, a drive through differential, a drive shaft, and/or still other components. The cooling system 1000 may include various cooling components including a fan, a radiator, fluid conduits, and/or still other components. The braking system 1200 may include various braking components such as brakes (e.g., disc brakes, drum brakes, air brakes, etc.), rotors, brake lines, brake pedals, and/or still other components. The steering assembly 1400 may include various steering components such as a steering wheel, a steering shaft, a steering rack, a power steering pump, tie rods, and/or still other components. As shown in FIGS. 1 and 3-5, the vehicle 100 includes a suspension system, shown as suspension system 1600. The suspension system 1600 may include various suspension components such as coilover spring-shocks, upper control arms, lower control arms, and/or still other components.

As shown in FIGS. 1-3 and 6, the frame 200 defines an axis, shown as longitudinal axis 202. The longitudinal axis 202 may be generally aligned with a frame component (e.g., a frame rail, etc.) of the frame 200 of the vehicle 100 (e.g., front-to-back, etc.). The longitudinal axis 202 may additionally or alternatively be defined by another feature or aspect of the vehicle 100 (e.g., a straight forward and/or rearward travel direction, etc.). As shown in FIGS. 1-5, the vehicle 100 includes a plurality of axles. The plurality of axles include a first axle, shown as front axle 110, a second axle, shown as first rear axle 120, and a third axle, shown as second rear axle 130. According to an exemplary embodiment, the front axle 110, the first rear axle 120, and the second rear axle 130 engage and support the frame 200 of the vehicle 100 via the suspension system 1600. In other embodiments, the vehicle 100 includes only one of the first rear axle 120 and the second rear axle 130 (e.g., only the second rear axle 130 and not the first rear axle 120, only the first rear axle 120 and not the second rear axle 130, etc.). The vehicle 100 may thereby be a two-axle vehicle. The “axles” outlined herein may include solid axle configurations and/or may include pairs of axles (e.g., pairs of half shafts, etc.) each having a set of constant velocity joints and coupling differentials to pairs of hub assemblies, according to various alternative embodiments.

As shown in FIGS. 1-5, each of the front axle 110, the first rear axle 120, and the second rear axle 130 includes tractive assemblies, shown as wheel and tire assemblies 140. The wheel and tire assemblies 140 each have a wheel and a tire. In some embodiments, the wheel is a multi-fit wheel configured to couple to various wheel hubs having different lug bolt patterns, as disclosed in U.S. patent application Ser. No. 16/050,100, filed Jul. 31, 2018, which is incorporated herein by reference in its entirety. In other embodiments, the traditional pneumatic tires of the wheel and tire assemblies 140 are replaced with non-pneumatic tires (i.e., airless tires). The vehicle 100 may thereby include non-pneumatic tires. In still other embodiments, the vehicle 100 additionally or alternatively includes track elements. The front axle 110, the first rear axle 120, and the second rear axle 130 may additionally include the brakes of the braking system 1200, gear reductions, the steering components of the steering assembly 1400, wheel hubs, the suspension components of the suspension system 1600 (e.g., independent suspension components, etc.), and/or other features.

According to an exemplary embodiment, the powertrain 800 is configured to drive each of the front axle 110, the first rear axle 120, and the second rear axle 130 such that the vehicle 100 is a 6×6 vehicle (e.g., six-wheel-drive, all-wheel-drive, etc.). By way of example, the powertrain 800 may be at least selectively coupled to the front axle 110, the first rear axle 120, and the second rear axle 130. Such a 6×6 arrangement may provide increased terrainability, traction, etc. for the vehicle 100 relative to a 2×6 variant, a 4×6 variant, a 2×4 variant, and/or a 4×4 variant. In other embodiments, the powertrain 800 is configured to drive only two of the front axle 110, the first rear axle 120, and the second rear axle 130 (e.g., only the first rear axle 120 and the second rear axle 130 are driven, only the front axle 110 and the first rear axle 120 are driven, only the front axle 110 and the second rear axle 130 are driven, etc.) such that the vehicle 100 is a 4×6 vehicle (e.g., rear-wheel-drive, four-wheel-drive, etc.). In still other embodiments, the powertrain 800 is configured to drive only one of the front axle 110, the first rear axle 120, and the second rear axle 130 (e.g., only the front axle 110 is driven, only the first rear axle 120 is driven, only the second rear axle 130 is driven, etc.) such that the vehicle 100 is a 2×6 vehicle (e.g., front-wheel-drive, two-wheel-drive, etc.). Such a 4×6 or 2×6 arrangement may require a less complex powertrain 800 and/or a powertrain 800 having reduced costs while meeting the various needs of the vehicle 100. In some embodiments, the powertrain 800 is reconfigurable between a 6×6 mode, a 4×6 mode, and/or a 2×6 mode such that the powertrain 800 may drive a varying number of axles based on the current mode of operation thereof. In one embodiment, the powertrain 800 is selectively reconfigurable between the 6×6 mode, the 4×6 mode, and/or the 2×6 mode in response to an operator input to change a mode of operation of the powertrain 800 between the 6×6 mode, the 4×6 mode, and/or the 2×6 mode. In another embodiment, the powertrain 800 is automatically and adaptively reconfigurable between the 6×6 mode, the 4×6 mode, and/or the 2×6 mode by a control system based on the current powertrain needs of the vehicle 100 (e.g., the 6×6 mode may be engaged in response to the vehicle 100 encountering rough terrain, the 2×6 mode may be engaged in response to the vehicle 100 traveling on smooth ground, etc.). Switching between various modes of operation may improve the efficiency of the vehicle 100 (e.g., improved fuel efficiency, etc.) and/or provide other benefits (e.g., reduce wear on certain components of the vehicle 100, etc.).

As shown in FIGS. 4-6, the vehicle 100 has a width W. The width W as used herein may be the overall width of the vehicle 100 between outermost points on each lateral side of the vehicle 100. According to an exemplary embodiment, the width W of the vehicle 100 is greater than that of a UTV. By way of example, UTVs may typically have a maximum width of less than 65 inches (e.g., 64 inches, etc.) such that they satisfy DNR trail regulations. Such regulations may require that vehicles using DNR trails have a width of less than 65 inches. In one embodiment, the width W of the vehicle 100 is 72 inches. In another embodiment, the width W of the vehicle 100 is 80 inches. In other embodiments, the width W of the vehicle 100 is between 70 inches and 80 inches (e.g., 70, 72, 74, 76, 78, 80, etc. inches). In still other embodiments, the width W of the vehicle 100 is between 60 inches and 70 inches (e.g., 60, 62, 64, 66, 68, 70, etc. inches). In some embodiments, the frame 200 is modular and has a width that is selectively variable to provide various vehicle configurations (e.g., different widths based on customer needs, etc.). According to an exemplary embodiment, increasing the width W of the vehicle 100 relative to UTVs facilitates transporting the vehicle 100 on a car carrier truck and/or trailer. By way of example, car carrier trucks and/or trailers may have tracks spaced to accommodate the track width of on-road automotive vehicles. UTVs, having a much smaller width and thereby a lesser track width than an automotive vehicle, may not bridge the gap between the tracks, and UTVs may not be transportable onboard such car carrier trucks and/or trailers. Advantageously, the vehicle 100, having a greater width W than UTVs and thereby a greater track width, is transportable upon a car carrier truck and/or trailer as it fits onto the spaced tracks of such car carrier trucks and/or trailers.

According to an exemplary embodiment, various components of the vehicle 100 (e.g., the frame 200, the cab 400, the rear module 600, the powertrain 800, the suspension system 1600, etc.) are designed to be more robust and rugged relative to components of UTVs. By way of example, panels of the cab 400 and/or the rear module 600 (e.g., the hood, fenders, bed, etc.) may be functional, high strength steel components, rather than plastic paneling as provided upon UTVs. Such plastic paneling may primarily provide only stylistic, aesthetic features. In some embodiments, at least some of the paneling of the vehicle 100 include plastic (e.g., plastic paneling, sheet metal paneling with a plastic skin, etc.). According to an exemplary embodiment, the more robust components of the vehicle 100 including the frame 200, the suspension system 1600, the cab 400, and the rear module 600, in combination with the front axle 110, the first rear axle 120, and the second rear axle 130, provide a higher payload capacity rating (e.g., including occupants, gear, modules, etc.) relative to UTVs. Payload capacity rating as used herein may be the amount of weight the vehicle 100 is capable of carrying, including passengers and cargo within the cab 400 and the rear module 600, within a preselected engineering factor or design factor (e.g., an engineering factor or design factor of 1.2, 1.5, 2, etc.; an engineering factor or design factor of “X” such that the vehicle 100 is actually capable of carrying “X” times the payload capacity rating from an engineering perspective; etc.). Therefore, the vehicle 100 may be capable of carrying greater payloads than the payload capacity rating that is advertised to the end consumer. By way of example, the vehicle 100 may have a payload capacity rating greater than 1,500 pounds (e.g., but less than 4,000 pounds, etc.). In one embodiment, the vehicle 100 has a payload capacity rating of at least 3,200 pounds. In some embodiments, the vehicle 100 has a payload capacity rating between 1,500 pounds and 3,200 pounds (e.g., 1,750, 2,000, 2,500, 3,000, etc. pounds).

According to an exemplary embodiment, the vehicle 100 is configured to provide increased off-road mobility relative to a vehicle having a similar wheelbase (e.g., the distance between the front-most to the rearmost axle, the distance between the front axle 110 and the second rear axle 130, etc.) that has only two axles (e.g., a 4×4 UTV having a similar wheelbase, etc.). The vehicle 100 provides significantly greater payloads by leveraging three axles, particularly designed (e.g., certain, additional, more robust, etc.) components, and/or independent suspension. For example, as shown in FIGS. 8A and 8B, vehicles having the same wheel base WB as the vehicle 100, but only including two axles, have reduced ground clearance GC₁ on uneven ground relative to the three-axle configuration of the vehicle 100, which has an increased ground clearance GC₂. The first rear axle 120 of the vehicle 100 effectively increases the ground clearance of the vehicle 100 in such scenarios by reducing the effective wheelbase WB_(eff) of the vehicle 100 to the distance between the front axle 110 and the first rear axle 120. The vehicle 100 having three axles also more evenly distributes loading throughout the vehicle 100 and facilitates sizing the components of the vehicle 100 to that of a traditional UTV, even with the increased payload capacity rating. A traditional two-axle or three-axle UTV would require components to be of a larger scale (e.g., the scale of a three-quarter ton pickup truck, etc.) to provide a similarly high payload capacity rating.

Frame and Chassis

According to the exemplary embodiment shown in FIGS. 9-23, the frame 200 extends lengthwise along the longitudinal axis 202 and widthwise along a lateral axis 204. The longitudinal axis 202 extends perpendicular to the lateral axis 204. The frame 200 includes a first portion, shown as central portion 206, and a second portion, shown as cab support or cab portion 208. The central portion 206 extends along the length of the vehicle 100 (i.e., parallel to the longitudinal axis 202) from the front-most part of the frame 200 to the rearmost part of the frame 200. The cab portion 208 is coupled to the central portion 206 and extends laterally outward (i.e., parallel to the lateral axis 204) from the central portion 206.

Many of the components of the frame 200 are arranged symmetrically about the longitudinal axis 202. To facilitate description of these components, the term “corresponding” as used hereinafter may refer to a component disposed on the same lateral side of the longitudinal axis 202. By way of example, in the phrase “component A is coupled to the corresponding component B,” component A and component B are both located on the same lateral side of the longitudinal axis 202.

As shown in FIGS. 9 and 11, the central portion 206 includes a pair of frame rails 210 that extend along the longitudinal axis 202. The frame rails 210 extend from a front portion of the frame 200 to a rear portion of the frame 200. The frame rails 210 each include a first tubular member, shown as lower rail 212, a second tubular member, shown as front upper rail 214, and a third tubular member, shown as rear upper rail 216. The front upper rail 214 is disposed directly forward of the rear upper rail 216. The front upper rail 214 and the rear upper rail 216 are offset vertically (i.e., perpendicular to the longitudinal axis 202 and the lateral axis 204) above the lower rail 212. The lower rail 212 extends farther rearward than the rear upper rail 216.

As shown in FIGS. 11 and 12, the lower rail 212, the front upper rail 214, and the rear upper rail 216 extend parallel to the longitudinal axis 202 except at a first longitudinal position 217, a second longitudinal position 218, a third longitudinal position 219, and a fourth longitudinal position 220. Additionally, a portion 222 of one of the lower rails 212 bows outward (e.g., to provide clearance for another component, such as an engine of the powertrain 800, etc.) such that it is not parallel to the front upper rails 214. Near the rear end of the frame 200, the lower rails 212 and the rear upper rails 216 extend parallel to one another (e.g., except for the portion 222) and have an overall width W₁. At the first longitudinal position 217, the lower rail 212 and the rear upper rail 216 bend laterally outward. Between the first longitudinal position 217 and the second longitudinal position 218, the lower rails 212 and the rear upper rails 216 extend parallel to one another and have an overall width W₂. At the second longitudinal position 218, the rear upper rails 216 terminate and meet (e.g., contact, couple to, etc.) the front upper rails 214. The front upper rails 214 extend upward from the lower rails 212 and bend to be in line with the rear upper rails 216. Accordingly, forward of the second longitudinal position 218, the front upper rails 214 and the rear upper rails 216 are in line with one another (e.g., each have the overall width W₂). At the third longitudinal position 219, the lower rails 212 bend laterally inward, however, the front upper rails 214 do not bend laterally. Forward of the third longitudinal position 219, the lower rails 212 have an overall width W₃. Accordingly, width W₂ is greater than both width W₁ and width W₃. Width W₁ may be greater than, equal to, or less than width W₃. The first longitudinal position 217 is disposed proximate (e.g., immediately rearward of) a rear end of the cab portion 208. Accordingly, the first longitudinal position 217 may be located longitudinally between the cab 400 and the rear module 600. The second longitudinal position 218 is disposed directly below the cab portion 208. The third longitudinal position 219 is disposed proximate (e.g., directly below) a front end of the cab portion 208.

As shown in FIG. 12, rearward of the fourth longitudinal position 220, an overall height h₁ extends between the lower surfaces of the lower rails 212 and the upper surfaces of the front upper rails 214 and the rear upper rails 216. At the fourth longitudinal position 220, the front upper rails 214 bend upward. Forward of the fourth longitudinal position 220, an overall height h₂ extends between the lower surfaces of the lower rails 212 and the upper surfaces of the front upper rails 214, where the height h₂ is greater than the height h₁. The fourth longitudinal position 220 may be forward of the third longitudinal position 219.

As shown in FIGS. 9, 10, 15, and 16, the frame rails 210 each include a first sheet or panel, shown as side panel 230, a second sheet or panel, shown as side panel 232, and a third sheet or panel, shown as side panel 234. The side panel 230, the side panel 232, and the side panel 234 extend between and couple the lower rail 212 to the front upper rail 214 and the rear upper rail 216. The side panel 230, the side panel 232, and the side panel 234 extend laterally outward of the lower rail 212, the front upper rail 214, and the rear upper rail 216. The side panel 230 is disposed partially forward of the side panel 232, and the side panel 232 is disposed forward of the side panel 234. The side panel 230, the side panel 232, and the side panel 234 act as web members to increase the bending resistance of the frame rails 210 as compared to the lower rails 212, the front upper rails 214, and the rear upper rails 216 alone. Accordingly, the side panel 230, the side panel 232, and the side panel 234 increase the payload capacity of the vehicle 100. Advantageously, this increased payload capacity facilitates the use of vehicle 100 in certain applications that would not be suitable for a UTV. By way of example, the vehicle 100 may be used in a defense application to transport a large number of passengers (e.g., 8, 9, 10, 11, 12, etc. passengers) to an off-road location. By way of another example, the vehicle 100 may be used in construction, firefighting, rescue, defense, agriculture, and event management applications when transporting a large payload to an off-road location.

As shown in FIGS. 10 and 12, the side panels 230 extend between the lower rails 212 and the front upper rails 214 near a front end of the frame 200. The side panels 230 each define an aperture 236 configured to receive a component (e.g., the front axle 110). A pair of lower mounting brackets, shown as suspension mounts 240, and a pair of upper mounting brackets, shown as suspension mounts 242 extend laterally outward from each side panel 230. The suspension mounts 240 may be coupled to the side panels 230, may be coupled to the lower rail 212, and/or may extend across the frame 200 and couple to one another (e.g., such that two suspension mounts 240 form a continuous cross member). The suspension mounts 242 may be coupled to the side panels 230, may be coupled to the front upper rail 214, and/or may extend across the longitudinal axis 202 and couple to one another (e.g., such that two suspensions mounts 242 form a continuous cross member). The suspension mounts 240 and the suspension mounts 242 each define apertures to facilitate rotatably coupling a component of the suspension system 1600 (e.g., a control arm, etc.) to the frame 200.

A portion of each side panel 232 extends along the corresponding front upper rail 214 forward of the fourth longitudinal position 220. From there, each side panel 232 extends rearward of the third longitudinal position 219, where each side panel 232 connects with the corresponding lower rail 212 and the corresponding rear upper rail 216. Near the first longitudinal position 217, each side panel 232 extends above the front upper rail 214 and the rear upper rail 216 and bends inward, forming a substantially horizontal flange or tab 244 and a substantially vertical flange or tab 246. The tabs 244 and the tabs 246 increase the resistance of the frame rails 210 to bending, thereby increasing the payload capacity of the frame 200. In some embodiments, each tab 244 is coupled to the corresponding tab 246. The tab 244 and the tab 246 may additionally facilitate coupling other components to the frame 200. By way of example, the tabs 244 and/or the tabs 246 may be fastened to the rear module 600.

The side panels 234 extend between the first longitudinal position 217 and a rear end of the frame 200. In some embodiments, each side panel 234 (e.g., the side panel 234 associated with a particular frame rail 210) is made from a single piece of material. In other embodiments, each side panel 234 is made up of multiple pieces of material (e.g., to minimize material waste during manufacturing). Near the first longitudinal position 217, each side panel 234 extends above the rear upper rail 216 and bends inward, forming a substantially vertical flange or tab 248. The tabs 248 increase the resistance of the frame rails 210 to bending, thereby increasing the payload capacity of the frame 200. The tabs 248 may be coupled to other components of the frame 200 (e.g., the support member 260, etc.) or other subsystems of the vehicle 100 (e.g., the rear module 600, etc.). A plurality of (e.g., 2, 4, etc.) lower mounting brackets, shown as suspension mounts 250, and a plurality of (e.g., 2, 4, etc.) upper mounting brackets, shown as suspension mounts 252 extend laterally outward from each side panel 234. The suspension mounts 250 may be coupled to the side panels 234 and/or the lower rail 212. As shown in FIG. 9, each suspension mount 250 extends across the longitudinal axis 202 (e.g., such that two opposing suspensions mounts 250 form a continuous cross member). The suspension mounts 252 may be coupled to the side panels 234 and/or the rear upper rail 216. In some embodiments, the suspension mounts 252 may extend across the longitudinal axis 202 (e.g., such that two opposing suspensions mounts 252 form a continuous cross member). The suspension mounts 250 and the suspension mounts 252 each define apertures to facilitate rotatably coupling a component of the suspension system 1600 (e.g., a control arm) to the frame 200. In embodiments that only include one rear axle, one or more of the suspension mounts 250 and/or the suspension mounts 252 may be omitted.

As shown in FIGS. 9 and 10, the frame 200 includes a tubular member, shown as support member 260. The support member 260 may be configured to support the rear module 600. The support member 260 may cooperate with lower rails 212 to support components of the powertrain 800 (e.g., an engine, etc.). In some embodiments, the frame 200 is configured to support multiple different engines (e.g., different sizes, different shapes, etc.). The support member 260 includes a pair of longitudinal portions 262 extending parallel to the longitudinal axis 202 and a lateral portion 264 extending parallel to lateral axis 204 and coupled to the longitudinal portions 262. Accordingly, the support member 260 forms a “U-shape.” The longitudinal portions 262 are disposed laterally outside of the frame rails 210 and extend between a rear end of the frame 200 and the first longitudinal position 217. Near a rear end, each longitudinal portion 262 defines an aperture that receives a pin 266. The pins 266 extend laterally from both sides of each longitudinal portion 262. The pins 266 may be configured to couple (e.g., rotatably, pivotally, etc.) the rear module 600 to the frame 200.

As shown in FIGS. 9 and 10, the lateral portion 264 is received by and coupled to the side panels 232 and the side panels 234. The frame 200 further includes a pair of tubular members, shown as braces 268. The braces 268 extend between the lateral portion 264 and the location where the front upper rail 214 and the rear upper rail 216 meet (e.g., at the second longitudinal position 218). The braces 268 couple at least one of the front upper rail 214 and the rear upper rail 216 to the lateral portion 264. The frame 200 further includes a first plate or tubular member, shown as cross member 270, and a second plate or tubular member, shown as cross member 272. The cross member 270 and the cross member 272 extend laterally between the longitudinal portions 262. In some embodiments, the cross member 270 and the cross member 272 couple the longitudinal portions 262 together. The cross member 270 is longitudinally offset forward of the cross member 272. In some embodiments, the support member 260, the cross member 270, and/or the cross member 272 are substantially level with one another to facilitate evenly distributing load from the rear module 600.

As shown in FIGS. 9 and 10, the frame 200 further includes a pair of bent sheet components, shown as vertical supports 274. The vertical supports 274 extend between the frame rails 210 and the support member 260. The vertical supports 274 extend to a top surface of the corresponding lower rail 212. Each side panel 234 extends along a surface of the corresponding vertical support 274 that faces laterally outward. In some embodiments, each rear upper rail 216 extends to the corresponding vertical support 274. Accordingly, each vertical support 274 may be coupled to the corresponding lower rail 212, the corresponding rear upper rail 216, and/or the corresponding side panel 234. Each vertical support 274 extends along an underside of the cross member 270 and the corresponding longitudinal portion 262. In some embodiments, each vertical support 274 extends along a side of the corresponding longitudinal portion 262 that faces laterally outward. Accordingly, each vertical support 274 may be coupled to one or both of the cross member 270 and the support member 260. The frame 200 further includes a tubular member, shown as cross member 276, that extends between and couples to both of the vertical supports 274.

As shown in FIGS. 9 and 14, the frame 200 further includes an attachment mechanism, shown as hitch receiver 280. The hitch receiver 280 is a tubular member configured to receive an adapter (e.g., a ball mount, a pintle hook, etc.) to connect a trailer to the frame 200. The hitch receiver 280 may be configured (e.g., sized, etc.) to receive an adapter of standard size. The hitch receiver 280 may include one or more apertures configured to receive a pin to couple an adapter to the hitch receiver 280. In some embodiments, the hitch receiver 280 is configured to support a greater towing capacity than that of a UTV. In one embodiment, the hitch receiver 280 has a towing capacity of at least 2,500 pounds. In some embodiments, the hitch receiver 280 has a towing capacity of more than 1,000 pounds (e.g., 1,250, 1,500, 2,000, 2,500, 3,000, etc. pounds). The hitch receiver 280 is received by a plate or bent sheet component, shown as hitch plate 282. The hitch plate 282 is coupled to the hitch receiver 280 and at least one of the lower rails 212 and the side panels 234 such that the hitch plate 282 distributes a load on the hitch receiver 280 between the frame rails 210. The hitch plate 282 is located near the rear end of the frame 200.

As shown in FIG. 9, the frame 200 further includes a pair of attachment members or tow eyes, shown as tie downs 284. Each tie down 284 may be included in the corresponding frame rail 210. The tie downs 284 are located between the hitch plate 282 and the side panels 234. The tie downs 284 may be coupled to the hitch plate 282, to the corresponding side panel 234, and/or to the corresponding lower rail 212. The tie downs 284 each define an aperture configured to receive an attachment device (e.g., a hook, a chain, a rope, a cable, a strap, etc.). The tie downs 284 facilitate connecting the vehicle 100 to another object (e.g., while the vehicle 100 tows the other object, while the other object transports or tows the vehicle 100, etc.). By way of example, a user may attach another vehicle to the vehicle 100 by hooking a strap into the tie downs 284 (e.g., to apply a force to an immobilized vehicle). By way of another example, a user may tie ropes through the tie downs 284 to secure the vehicle 100 onto a trailer of another vehicle for transport. In some embodiments, the tie downs 284 are configured to conform to one or more standards (e.g., MIL-209).

As shown in FIG. 9, the frame 200 further includes a tubular member, shown as cross member 286, and a pair of bent sheet components, shown as vertical supports 288. The cross member 286 extends between both of the side panels 234 near the rear of the frame 200. The cross member 286 may be coupled to one or more of the lower rail 212, the side panel 234, and the hitch plate 282. The cross member 286 is offset longitudinally forward of the hitch plate 282, and a top surface of the cross member 286 is substantially level with a top surface of the hitch plate 282. The vertical supports 288 extend between the hitch plate 282, the cross member 286, and the support member 260. The vertical supports 288 rest on a top surface of the hitch plate 282 and a top surface of the cross member 286. Each vertical support 288 may be coupled to the corresponding side panel 234, the hitch plate 282, and/or the cross member 286. Each vertical support 288 extends along an underside of the cross member 272 and an underside of the corresponding longitudinal portions 262. Each vertical support 288 extends along a side of the cross member 272 that faces rearward and along a side of each longitudinal portion 262 that faces laterally outward. Accordingly, each vertical support 288 may be coupled to one or both of the cross member 272 and the support member 260.

As shown in FIGS. 10 and 13, the frame 200 further includes a bent sheet component, shown as winch panel 290. The winch panel 290 is located near the front end of the frame 200. The winch panel 290 extends along a top side of the front upper rails 214, along a front side of the front upper rails 214 and the lower rails 212, and along an underside of the lower rails 212. Accordingly, the winch panel 290 may be coupled to the front upper rails 214 and/or the lower rails 212. As shown in FIG. 1, the winch panel 290 is configured to support a winch 292. The winch 292 is configured to apply a retracting force on a tensile member (e.g., a cable, a rope, a chain, etc.). As shown in FIG. 13, the winch panel 290 defines a number of apertures 294 configured to receive fasteners that couple the winch 292 to the winch panel 290. As shown in FIG. 13, the winch panel 290 further defines an aperture 296 located between the apertures 294. A first portion of the winch 292 (e.g., a drum, a motor, a gearbox, a spool of cable, etc.) is disposed inside of the frame 200 (e.g., along a rear, inner surface of the winch panel 290) and a second portion of the winch 292 (e.g., a bearing portion, etc.) is disposed outside of the frame 200 (e.g., along a front, outer surface of the winch panel 290). Accordingly, the tensile member of the winch 292 extends from the first portion of the winch 292 through the aperture 296 where an operator may access the tensile member. The winch 292 is configured to apply a retracting force to the tensile member in a substantially longitudinal direction. Advantageously, an arrangement where the winch 292 is disposed inside of the frame 200 facilitates a reduction in overall length of the vehicle 100 when compared to a conventional arrangement where a winch is disposed entirely or almost entirely outside the frame. In some embodiments, the winch 292 is disposed entirely forward of the winch panel 290 such that the winch 292 is disposed entirely outside of the frame 200.

As shown in FIGS. 10 and 12, the frame 200 further includes a pair of attachment members or tow eyes, shown as tie downs 300. Each tie down 300 may be included in the corresponding frame rail 210. The tie downs 300 are located at the front end of each frame rail 210 and extend through apertures in the winch panel 290. The tie downs 300 are located laterally inward of the side panels 230. The tie downs 284 may be coupled to the winch panel 290, to the corresponding side panel 230, to the corresponding lower rail 212, and/or to the corresponding rear upper rail 216. The tie downs 300 each define an aperture configured to receive an attachment device (e.g., a hook, a chain, a rope, a cable, a strap, etc.). The tie downs 300 facilitate connecting the vehicle 100 to another object (e.g., while the vehicle 100 tows the other object, while the other object transports or tows the vehicle 100, etc.). By way of example, a user may attach another vehicle to the vehicle 100 by hooking a strap into the tie downs 300 (e.g., to apply a force to an immobilized vehicle). By way of another example, a user may tie ropes through the tie downs 300 to secure the vehicle 100 onto a trailer of another vehicle for transport. In some embodiments, the tie downs 300 are configured to conform to one or more standards (e.g., MIL-209).

In some embodiments, the frame 200 is modular and has a width that is selectively variable to provide various vehicle configurations (e.g., different widths based on customer needs, etc.). The frame 200 is shown in a first configuration in FIGS. 9-19 and in a second configuration in FIGS. 20-22. It should be understood, however, that the frame 200 may be reconfigurable into yet other configurations. FIG. 23 shows both configurations of the frame 200 overlaid atop one another. The central portion 206 of the frame 200 is mostly unchanged between the two configurations. Each configuration of the frame 200 includes a different cab portion 208. Utilizing a common central portion 206 facilitates customizing the vehicle 100 to the needs of a specific customer while minimizing the number of different assemblies that are manufactured. By way of example, using the same frame rails 210 and the same spacing between the frame rails 210 throughout the different configurations of the frame 200 may facilitate using many of the same components in the various configurations for the other subsystems of the vehicle 100 (e.g., the powertrain 800, the suspension system 1600, etc.) throughout each configuration.

As shown in FIG. 23, the first configuration has a width W_(A) and the second portion has a width W_(B). The widths W_(A) and W_(B) as used herein may be the overall width of the frame 200 between outermost points on each lateral side of the frame 200. The width W_(A) is larger than the width W_(B). In some embodiments, the width W_(A) is greater than 65 inches (e.g., at least 72 inches, etc.). In some embodiments, the width W_(B) is at least 60 inches, but less than 65 inches. The greater width of the first configuration may facilitate placing an additional passenger in the cab 400 (e.g., for a total of 3 passengers in the cab 400).

As shown in FIG. 23, both the first configuration and the second configuration have the same length L. The length L as used herein may be the overall length of the frame 200 between outermost points on each longitudinal side of the frame 200. The length remains constant between the first configuration and the second configuration, as the length L is defined by components of the central portion 206 that do not change between the first configuration and the second configuration (e.g., the tie downs 300 and the support member 260).

As shown in FIGS. 9-19, the frame 200 is in the first configuration. In the first configuration, the cab portion 208 of the frame 200 includes a pair of bent sheet components, tubular members, or plates, shown as floor supports 320. The floor supports 320 extend longitudinally along the length of the cab 400 and are located proximate a lateral side of the cab 400. The floor supports 320 are located directly below the level of the floor in the cab 400. Accordingly, an upper surface of each floor support 320 may be substantially level with the upper surfaces of the front upper rails 214 and the rear upper rails 216. The floor supports 320 may be coupled to and support a floor surface of the cab 400. Each floor support 320 is coupled to the central portion 206 of the frame 200 by a pair of tubular members, shown as lateral supports 322. The lateral supports 322 extend from the corresponding lower rail 212 to an underside of the corresponding floor support 320. The lateral supports 322 are each coupled to a lateral side of the corresponding lower rail 212. To further support the cab portion 208, the central portion 206 includes a first pair of tubular members, shown as braces 324, and a second pair of tubular members, shown as braces 326. The braces 324 and the braces 326 are included in both configurations of the frame 200. The braces 324 extend forward of the front lateral supports 322 and couple the front lateral supports 322 to the corresponding lower rail 212. The braces 326 extend rearward of the rear lateral supports 322 and couple the rear lateral supports to the corresponding lower rail 212.

As shown in FIGS. 9 and 17, in the first configuration, the cab portion 208 further includes a plate or sheet component, shown as floor pan 328. Each floor pan 328 extends along an underside of the corresponding lateral supports 322 and the corresponding floor support 320. Each floor pan 328 may be coupled to the corresponding floor support 320, the corresponding lateral supports 322, and/or the corresponding lower rail 212. In some embodiments, the floor pans 328 support a fuel tank and/or a battery. The cab portion 208 further includes multiple tubular members, shown as cross members 330. A pair of cross members 330 extend between and couple each floor support 320 and the corresponding front upper rail 214. Another pair of cross members 330 extend between and couple the front upper rails 214 and are in line with the other cross members 330. In some embodiments, the cross members 330 are replaced with a pair of cross members 330 that extend between and couple the floor supports 320. In some embodiments, a pair of cross members 330 extend between the floor supports 320, coupling the floor supports 320 to the front upper rails 214. The cross members 330 are located directly below the level of the floor in the cab 400. Accordingly, an upper surface of each cross member 330 may be substantially level with the upper surfaces of the front upper rails 214.

As shown in FIGS. 9 and 17, in the first configuration, the cab portion 208 further includes a pair of tubular members, shown as rear cab supports 332. The rear cab supports 332 are located near a rear end of the floor supports 320. Each rear cab support 332 extends laterally outward (e.g., substantially horizontally) from the corresponding rear upper rail 216. An upper surface of each rear cab support 332 may be substantially level with upper surfaces of the floor supports 320 and upper surfaces of the front upper rails 214 and the rear upper rails 216. A portion of each floor support 320 is cut away such that the floor support 320 receives the corresponding rear cab support 332. Each rear cab support 332 is coupled to the corresponding rear upper rail 216 and to the corresponding floor support 320. Above the corresponding floor support 320, the rear cab supports 332 bend upward such that the rear cab supports 332 each include a substantially vertical portion. In some embodiments, the substantially vertical portion is directly coupled to a vertical support member of the cab 400.

As shown in FIGS. 9 and 17, in the first configuration, the cab portion 208 further includes tubular members, shown as front cab supports 334. The front cab supports 334 are each coupled to the corresponding floor support 320 near a front side and a laterally outward side of the corresponding floor support 320.

According to an exemplary embodiment, the first rear differential output 854 is configured to couple to a final drive (e.g., half shafts coupled to the wheel and tire assemblies 40, etc.) of the first rear axle 120. The rear differential 850 may be configured to provide at least a portion (e.g., a first portion, etc.) of the mechanical energy received from the rear drive shaft 840 to the first rear axle 120 to facilitate driving the first rear axle 120 directly with the rear differential 850. In some embodiments, the rear differential 850 is an unlocking differential that facilitates relative movement between the wheel and tire assemblies 40 of the first rear axle 120. In other embodiments, the rear differential 850 is a locking differential.

As shown in FIG. 60, the front differential 870 includes an input, shown as front differential input 872, and an output, shown as front differential output 874. As shown in FIGS. 57-60, the powertrain 800 includes a second drive shaft, shown as front drive shaft 860, having a first end, shown as rear end 862, and an opposing second end, shown as front end 864. The front drive shaft 860 extends between the rear differential 850 and the front differential 870 such that the rear end 862 of the front drive shaft 860 is coupled to the second rear differential output 856 and the front end 864 of the front drive shaft 860 is coupled to the front differential input 872. The rear differential 850 may be configured to provide at least a portion (e.g., a second portion, etc.) of the mechanical energy received from the rear drive shaft 840 to the front drive shaft 860 to facilitate driving the front differential 870 directly with the rear differential 850. The rear differential 850 may thereby be configured as a drive-through differential.

According to an exemplary embodiment, the front differential output 874 is configured to couple to a final drive (e.g., half shafts coupled to the wheel and tire assemblies 40, etc.) of the front axle 110. The front differential 870 may be configured to provide to the mechanical energy received from the front drive shaft 860 to the front axle 110 to facilitate driving the front axle 110 directly with the front differential 870. In some embodiments, the front differential 870 is an unlocking differential that facilitates relative movement between the wheel and tire assemblies 40 of the front axle 110.

According to the exemplary embodiment shown in FIGS. 57-60, the transaxle 830, the rear drive shaft 840, the rear differential 850, the front drive shaft 860, and the front differential 870 facilitate actively driving the front axle 110, the first rear axle 120, and the second rear axle 130 such that the vehicle 100 is a 6×6 vehicle. In some embodiments, the powertrain 800 includes (i) a first clutch positioned between the transaxle 830 and the rear differential 850 and/or (ii) a second clutch positioned between the rear differential 850 and the front differential 870 such that the powertrain 800 of the vehicle 100 may be selectively and/or automatically reconfigurable between a 6×6 mode, a 4×6 mode, and/or a 2×6 mode of operation based on engagement and disengagement of the first clutch and/or the second clutch (e.g., disengagement of the first clutch may decouple the rear differential 850 and the front differential 870 from the transaxle 830, disengagement of the second clutch may decouple the front differential 870 from the rear differential 850, etc.).

In some embodiments, the powertrain 800 does not include at least one of the rear drive shaft 840, the rear differential 850, the front drive shaft 860, and the front differential 870. By way of example, the powertrain 800 may not include the rear differential 850 and the rear drive shaft 840. In such embodiments, the rear end 862 of the front drive shaft 860 may be coupled to the second transaxle output 834. The transaxle 830 may thereby be configured to provide at least a portion of the mechanical energy received from the transmission 820 to the front drive shaft 860 to facilitate driving the front differential 870 directly with the transaxle 830. The first rear axle 120 may thereby be a passive, non-driven axle such that the vehicle 100 is a 4×6 vehicle. By way of another example, the powertrain 800 may not include the front differential 870 and the front drive shaft 860. The front axle 110 may thereby be a passive, non-driven axle such that the vehicle 100 is a 4×6 vehicle and the rear differential 850 may be a non-drive-through differential. By way of yet another example, the powertrain 800 may not include the rear drive shaft 840, the rear differential 850, the front drive shaft 860, and the front differential 870 such that the front axle 110 and the first rear axle 120 are both passive, non-driven axles such that the vehicle 100 is a 2×6 vehicle.

Air Cleaner System

As shown in FIGS. 57, 58, and 60, the vehicle 100 includes an air cleaner system including an intake, shown as engine air intake 880, and a conduit, shown as air conduit 882, extending from the engine air intake 880 to the engine 810. According to an exemplary embodiment, the engine air intake 880 includes an air filter positioned to filter debris and particulates out of ambient air being drawn in by the engine air intake 880. The filtered air may be provided from the engine air intake 880 to the engine 810 by the air conduit 882 for combustion with the fuel within combustion cylinders of the engine 810. According to an exemplary embodiment, the engine air intake 880 is positioned under the dash of the cab 400. The engine air intake 880 may thereby be positioned such that the engine air intake 880 is sufficiently removed from dirty and/or dusty air the vehicle 100 may generate near the bottom and rear of the vehicle 100 while moving. Such positioning of the engine air intake 880 may thereby facilitate a fresher air intake, increasing the useful life of the air filter within the engine air intake 880, as well as providing cleaner air to the engine 810. In other embodiments, the engine air intake 880 is otherwise positioned (e.g., at the front of the vehicle 100 under the hood, etc.).

As shown in FIGS. 57-59, the engine 810 includes an exhaust, shown as exhaust system 890. The exhaust system 890 is configured to facilitate expelling combustion exhaust gases from the engine 810 into the ambient environment. The exhaust system 890 may include an exhaust manifold directly coupled to the engine 810, piping extending from the exhaust manifold, and/or a muffler positioned at the end of the piping. As shown in FIG. 58, the exhaust system 890 includes a conduit, shown as suction conduit 892, that branches off from the exhaust system 890 and connects to the engine air intake 880. The suction conduit 892 may branch off from the exhaust manifold, the muffler, and/or any suitable position along the exhaust system 890. As shown in FIG. 58, the suction conduit 892 includes a valve, shown as one-way valve 894, that restricts the flow of exhaust into the suction conduit 892. In other embodiments, the exhaust system 890 does not include the one-way valve 894. According to an exemplary embodiment, the flow of exhaust gases through the exhaust system 890 creates a vacuum across (i) an opening at which the suction conduit 892 meets the other portion of the exhaust system 890 and/or (ii) the one-way valve 894 (e.g., an exhaust Venturi, etc.). The vacuum provides suction within the engine air intake 880 and the suction conduit 892, pulling debris, dirt, particulates, etc. from the air filter of the engine air intake 880, effectively cleaning the air filter while the engine 810 of the vehicle 100 is running. The debris, dirt, particulates, etc. removed from the air filter may then flow through the suction conduit 892 and/or the one-way valve 894 into the exhaust gases of the exhaust system 890, and expelled into the ambient environment through the muffler of the exhaust system 890.

Cooling System

As shown in FIG. 61, the hood 170 and the front grille 172 cooperatively define an interior cavity, shown as front cavity 174, that receives the cooling system 1000. According to an exemplary embodiment, the cooling system 1000 is configured to thermally regulate (e.g., cool, etc.) the engine 810 of the powertrain 800. As shown in FIG. 61, the cooling system 1000 includes a mount, shown as radiator bracket 1002, that is coupled to the frame 200. In one embodiment, the radiator bracket 1002 is coupled to the frame 200 proximate the front grille 172. The cooling system 1000 includes a heat exchanger, shown as radiator 1004, that is coupled to the radiator bracket 1002; a driver, shown as fan 1006, positioned at (e.g., coupled to, etc.) a rearward side of the radiator 1004; and conduits, shown as fluid conduits 1008, extending from the radiator 1004 to the engine 810 of the powertrain 800. According to an exemplary embodiment, the radiator 1004 is configured to receive incoming air through the front grille 172 to reduce the temperature of a fluid (e.g., coolant, etc.) within the cooling system 1000 and thereby cool the engine 810 of the powertrain 800. The fan 1006 is configured to draw the incoming air through the radiator 1004. In other embodiments, the fan 1006 is positioned in front of the radiator 1004 such that the fan 1006 pushes air through the radiator 1004. In an alternative embodiment, the cooling system 1000 does not include the fan 1006. In such embodiments, the radiator 1004 may be liquid-cooled, rather than air-cooled. According to an exemplary embodiment, the fluid cooled by the radiator 1004 and/or the fan 1006 is delivered to the engine 810 of the powertrain 800 by the fluid conduits 1008 to thermally regulate the engine 810.

According to the exemplary embodiment shown in FIG. 61, the radiator 1004 is disposed (e.g., held by the radiator bracket 1002, etc.) at an angle θ relative to an axis, shown as vertical axis 1010 (i.e., the radiator 1004 is arranged in an angled and/or angularly offset orientation). According to an exemplary embodiment, the vertical axis 1010 is parallel to or substantially parallel to a central vertical axis of the front grille 172 (e.g., the front grille 172 is oriented substantially vertically, etc.). By way of example, the angle θ of the radiator 1004 may range from 0 degrees (e.g., vertical, etc.) to 75 degrees relative to the vertical axis 1010. In some embodiments, the angle θ of the radiator 1004 is between 30 degrees and 45 degrees relative to the vertical axis 1010 (e.g., 30, 35, 40, 45, etc. degrees or any angle therebetween). In other embodiments, the angle θ is between 15 degrees and 30 degrees relative to the vertical axis 1010 (e.g., 15, 20, 25, 30, etc. degrees or any angle therebetween). In still other embodiments, the angle θ of the radiator 1004 is between 45 degrees and 60 degrees relative to the vertical axis 1010 (e.g., 45, 50, 55, 60, etc. degrees or any angle therebetween). In yet other embodiments, the angle θ of the radiator 1004 is between 0 degrees and 15 degrees (e.g., 0, 5, 10, 15, etc. degrees or any angle therebetween). In yet still other embodiments, the angle θ is between 60 degrees and 75 degrees (e.g., 60, 65, 70, 75, etc. degrees or any angle therebetween).

Traditionally, radiators in UTVs or other off-road vehicles are arranged in a vertical orientation. Such a vertical orientation may require at least a portion of the hood of the UTV to be raised at the location of the radiator such the radiator can properly fit underneath the hood. Such a raised hood may disadvantageously raise the hood line of the hood and obstruct the vision and sight line of an operator of the UTV and reduce the drivability thereof. In some UTVs, the radiator may be moved further rearward (i.e., away from the front grille, away from the front end of the hood) to improve/lower the hood line. A radiator that is spaced from the front grille, however, has reduced performance and efficiency. According to an exemplary embodiment, angling the radiator 1004 of the vehicle 100 facilitates lowering the hood line of the hood 170. Lowering the hood line of the hood 170 advantageously increases the vision and sight line of an operator of the vehicle 100 to improve the drivability and maneuverability of the vehicle 100. While angling the radiator 1004 may reduce the performance of a radiator, angling the radiator 1004 facilitates increasing the cooling capacity thereof (e.g., by making the radiator 1004 larger, etc.) and positioning the radiator 1004 at the front end of the hood 170 (e.g., proximate the front grille 172, etc.) such that the performance thereof is similar to or improved relative to a vertically orientated radiator. As such, the radiator 1004 being positioned at the angle θ facilitates lowering the hood line of the hood 170 relative to traditional UTVs, while maintaining or improving the performance of the cooling system 1000.

In other embodiments, each of the front braking assembly 1210, the first rear braking assembly 1220, and the second rear braking assembly 1230 include drum brakes and/or still other types of brakes.

According to an exemplary embodiment, engagement of the brake pedal 1242 actuates one or more of the front braking assembly 1210, the first rear braking assembly 1220, and the second rear braking assembly 1230 (e.g., the brake calipers of the disc brakes 1240 thereof, etc.) to decelerate and/or stop the vehicle 100. By way of example, engagement of the brake pedal 1242 may actuate (i) all three of the front braking assembly 1210, the first rear braking assembly 1220, and the second rear braking assembly 1230, (ii) only the first rear braking assembly 1220 and the second rear braking assembly 1230, (iii) only the front braking assembly 1210 and the first rear braking assembly 1220, (iv) only the front braking assembly 1210 and the second rear braking assembly 1230, (v) only the front braking assembly 1210, (vi) only the first rear braking assembly 1220, or (vii) only the second rear braking assembly 1230.
